CSP Model 4mm Loco Kits

March 2019 - Released is the CSP18 kit. This is for the GWR 1361 0-6-0 Saddle Tank locomotive.
Also open for orders again is CSP15, Medina. We are sorry for this delay but we had problems finding the latest chassis etch. There were several films and all had slight variations but we had to make certain we had the correct one!

February 2019 - NEW ITEM - Steam and vacuum pipes have been added. CSP51.

1 January 2019 - NEW ITEM - We are pleased to announce that we have added a set of Fireirons to our range. Please see item CSP50.

2018- Upgrade for CSP03 Kerr Stewart Victory 0-6-0T has been produced. It now comes with a lost wax brass cast chimney, dome, safety valve and tank fillers!

Update 10/12/17

Well it never rains but it pours, or so they say!

First the bad news - the business computer was stolen when our vehicle was broken into. Unfortunately the backup system has failed so it is back to square one for so much work. Hours and hours of work on drawings will all have to be redone, once a new computer is up and running.

GOOD News: - The majority of CSP 4mm model information is on this site or on Philip's computer. What we have lost, at the moment, is copies of all the etch /films/plates/drawings we were working on so delays in sorting out some models is inevitable. Having had to take time out to deal with family commitments Philip is now hoping to be back at work more often so delivery time for orders will reduce. He also has access to e-mails now as well!

Wheels, motors and gearboxes.
We finally got a delivery from Markits so hopefully we have fulfilled all back order. Our intention is to move to Gibson wheels wherever possible. These are already used for P4 and some EM orders.
Motors - we have sourced a new six pole motor that appears to be more powerful than the Mashima 1020. It will be used in place of the Mashima as and when stocks run out. Mashima prices have already gone to silly levels so we are not buying anymore!
Gearboxes - at present most models use 38:1 gears from Markits and one of our etches. We intend to move to High Level units for all of our models along side the new motors. Newer kits already use them so it makes sense to try and standardise

At last our 'expert' webmaster has discovered why the site kept crashing. He is working hard to ensure it does not happen again.

Haye Development products have been taken over by David Geen. Please see his website for contact details.

All future new kits will come with lost wax castings exclusively, whitemetal will no longer be used.
We do hope to attend one or two shows during the year if we can.
Any enquiries you may have please feel free to e-mail or telephone us.

The current range of 4mm kits have been designed, for ease of assembly, with tabs and slots for location of parts. Loco bodies are of etched brass with etched nickel silver chassis. Components such as saddle tank, boiler, firebox, etc are predominantly pre-formed. Castings are of white metal or lost wax brass. Wheel bearings, handrail knobs and wire are included. Some kits contain sprung buffers. All parts, except wheels, gears, motor and pick-ups are present in a basic kit, and a "complete" kit contains all components to produce a running unpainted model. Comprehensive stage-by-stage instructions with exploded part diagrams ensure that construction is as easy as possible.
